In June 2020, State Impact of Pennsylvania stated that "In 1979, the EPA banned the use of PCBs, but they still exist in some products produced before 1979. They persist in the environment because they bind to sediments and soils. High exposure to PCBs can cause birth defects, developmental delays, and liver changes." [10]
PCBs share the basic chemical structure of biphenyl and one or more of the hydrogen atoms on the aromatic rings are replaced by chlorine atoms. [1] PCBs is in viscous liquid form at normal temperature and has a poor solubility in water. The aromatic hydrocarbon structure gives PCBs relatively high molecular stability.
The optimal temperature range is 400 °C (752 °F) to 700 °C (1,292 °F). This means that formation is highest when organic material is burned in less-than-optimal conditions such as open fires, building fires, domestic fireplaces, and poorly operated and/or designed solid waste incinerators. [ 3 ]
The PCBs came from the company's two capacitor manufacturing plants at Hudson Falls and Fort Edward, New York. [1] The U.S. Environmental Protection Agency (EPA) banned the manufacture of PCBs in 1979. [9] The bulk of the PCBs in the river were manufactured by Monsanto Co. under the brand names Aroclor 1242 and Aroclor 1016. [10]

Since being banned, the average human body burdens of DDT and PCB have been declining. [66] [173] [174] Since their ban in 1972, the PCB body burden in 2009 is one-hundredth of what it was in the early 1980s. On the other hand, monitoring programs of European breast milk samples have shown that PBDE levels are increasing.
If Bill 418 is approved, Sour Patch Kids, Starburst, Swedish Fish, and Trolli gummies would also be banned in the state due to the inclusion of titanium dioxide and other additives.
The Toxic Substances Control Act (TSCA) is a United States law, passed by the 94th United States Congress in 1976 and administered by the United States Environmental Protection Agency (EPA), that regulates chemicals not regulated by other U.S. federal statutes, [1] including chemicals already in commerce and the introduction of new chemicals.
